10. A 150.0mL sample of salt water is evaporated to dryness. A residue of salt weighing 27.9g is left behind. Calculate the percent mass/volume of the original salt water sample. 11. A solution is made by dissolving 0.900g of salt in 100.0mL of water. Assume that each milliliter of water weights 1.00g and that the final solution volume is 100.0mL. Calculate the %mass and %mass/volume for the solution.
